Hose CLAMP.

aaiaoia. I

To all whom 2'25 may concern:

Be it known that I, JosnrH GENTILE, ,a subject of the King of Italy, and a resident of the borough of Brooklyn, in the county of Kings and Stateof New York, have invented certain new and usefullmprovements in Hose Clamps, or which the follov ing is a specification.

This invention has as one of its objects to produce a hose'clamp for re-enforcing pliable hose made of textile fabric, whereby they are effectively stiffened, supported and protected from bursting or injury from the I Another purpose is to provide means, integrally combined with, the clamp, for .securing branch connections 'to the hose, holding the same in proximate engagement and protecting the joints. I

A furtherobject is to provide such devices in a plurality of forms, suited to varying conditions and circumstances, each type being self-conforming,capable of tight adjustment after assembling, and of ready application at any desired time.

These and other analogous objects are at tained by the novel constructions, combinations and arrangement of parts hereinafterdescribed and shown in th'e'accompanv ing'drawings,- for'ming a component part of the disclosure, and in which:-

Figure 11 is aside viewof a double or elongated type of inner element. a Figure 12 is a similar View of inner element. I p I Figure 13 is a transver e sectional View taken on line 13-13 of Figure 9.

This invention embodies improvements overmy invention for clamp described, illustrated and claimed in an application filed April 22nd, 1921. Serial #463,518.

In the drawings the numeral 20 designates in general a conventional type of explosion motor, together withits radiator 21, the same being engaged by'a pipe or hose 22 from which the heated water returns to a single the radiator and a circulatingpipe orliose 23 forcarrying the water back to the motor after being cooled by passing through the radiaton v j k c A small hose 2% leads fromthe pipe, or

hose 23 to a thermostat 25fconnectd with a the radiator, as shown in Figure 1,"these parts being of common use and formfno part of the invention, they being illustrated merely to indicateusesof the hose clamps.

Disposed on the hose 23 is al'typeof clamp shown in detail in Figure 8 and on the hose 22 is a simple form or clamp, such as is shown in Figures 2, 4, ory6.

Stated generally, all of the several types of clamp are composed or two main elements, respect1vely nnerand outer, and the bolts by which they are "constrained together or ends 32 and 33 containing perforations 34 g and the former of which are elo'ngated for a purpose further on apparent. Also in these plates, between the recesses 31 are figural openings 36 thereby reducing the Weight, and improvingthe appearance ofthe clamps. y H

The metal disposed midway between 'the lateral edges and ends ofthe openings 36 is pressed to produce cavities of uniform depths, and as shown in Figure 3, may extend from one tab to another'unbrokenly,

as at 37, or be divided into two sections, as at 38,in Figure 5. Attention is called to the extensions 39 and perforations 40 of the tabs 33 which will be referredtofurther, on.

Finally the central portion of the plates, lying between the tabs, are bent cylindrically and the top portions are extended 'in parallel outwardly and the perforations 3aand 35 brought into register to receive clamp bolts il fitted with wing nuts 42 and the bodies of the bolts may be provided with lugs entering the elongated perforations 34 to prevent them from turning when manipulating the nuts in adjusting the clamps, the finished forms of which are clearly evident in Figures 2 and A.

The. inner elements of the clamps are shown in Figures 11 and 12, the latter being used in connection with the outer elements just described, the same consisting of a rectangular blank bent cylindrically into a tube 43 open at its upper adjacent end 44: and sheared as at 45 to produce tabs 46 containing perforations d7, the ends of the tabs being turned reentrantly outward as at L8 and an indentation 49, constituting a detent made in the lip thus formed.

These blanks are suited to enter the cavi ties 37 or 38 and the tabs extended to be received between the tabs 34 and 35, the bolts passing through the perforation 4:7.

The longer inner elment, shown in Figure 11, is used in connection with the outer elements seen in Figures 6 and 7, the former of which is distinguished merely by having its expanded portion extended over the entire area between its marginal edges which fit the hose, while the form shown in Figure 7 is plainly cylindrical from end to end as at 51.

- As will be seen, the tabs 46 of the inner elements are received between the tabs 33 and 34; of the outer element and are in a manner positioned by the extensions 39,, which also act as guards for the elements 48, the detents 49 of which engage in the perforations 40.

Again referring to Figure 7, it will be noted that an extension 52 reaches from the center of the blank, which before bending is obviously shaped like a reversed T, the laterally extending arms of which are formed into an open ring 53 having outstanding clamp element 54 connected by a bolt as shown, for the purpose of engaging a branch to the main hose.

The general arrangement of clamps for this purpose is. shown in Figures 8, 9 and 10, the latter being a view of the flat blank similar to but longer than those previously described and containing duplicate parts.

' In addition the arm 52 extending from the central recess 81 at one edge, is formed with a strip 55 to be bent into a ring, as in Figures 8 and 9.

Also sheared 0n the lines 56, at the center of the plate are T shaped elements 57 and 57 bent to form rings as shown in these last named figures and clamped at their ends, this type of clamp being known as a cross, its application being seen in Figure 1.

A similar type of clamp may be provided without the sheared elements 57 and 57 having instead thereof a top central opening similar to that indicated in Figure 7.

In order to support as well as re-enforce a flexible hose or the like, the adaptation shown in Figure 14 may be used, the same consisting of an elongated guard or clamp 60composed of a plurality of elements 30 integrally connected, having cut out 36 and tabs clamped as described.

The recesses are suited to receive the shorter inner clamp element 43' and extending rearward or above these outer clamp elements are other, but smaller cylindrical elements 61 adapted to engage a red, tube or similar support 62 arranged parallel and contiguous to the hose 63 to which the clamp is engaged.

/Vhile certain preferred embodiments of this device have been shown and described, it will be understood that changes in form and details thereof may be made without departing from the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A hose clamp comprising substantially cylindrical inner and outer members, tabs on the outer member extending from its adjacent edges, tabs integrally formed from the bodies of said inner members opposite their adjacent edges, said inner tabs extending co-incidently between said outer tabs, co-operative detent elements engaging between said inner and outer tabs, and bolts for drawing each group of tabs together whereby the inner and outer elements of said cylindrical members are contracted in diameter.

2. A hose clamp comprising an outer cylindrical member formed to present recesses in its interior, tabs extending from its spaced longitudinal edges, one or more inner cylindrical members having spaced edges disposed oppositely to that of the outer member, tabs integrally formed with said inner members extending outwardly between the tabs of the outer member, all of said tabs having registering openings, bolts passing through the openings, and means preventing said bolts from turning while being tightened.
